we can set up a relation to solve this problem
If Calvin paints 
in 2 minutes
He will paint 
in 
minutes
By cross multiplying, we have

Answer:
120 lb of soybean meal
200 lb of cornmeal
Step-by-step explanation:
S = pounds of soybean meal
C = pounds of cornmeal
S + C = 320 → C = 320 – S
0.16S + 0.08C = 0.11 × 320 = 35.2
16S + 8C = 3520
16S + 8(320 – S) = 3520
16S + 2560 – 8S = 3520
8S + 2560 = 3520
8S = 960
S = 120
C = 320 – 120 = 200
